The Additron was an electron tube designed by Dr. Josef Kates, circa 1950, to replace the several individual electron tubes and support components required to perform the function of a single bit digital full adder.
The game machine controlled the lighting of an overhead display to show the progress of the game, and was built using a special electron tube, the Additron Tube, which Kates had invented.

It did make a widely publicized appearance at the 1950 Canadian National Exhibition operating an electronic game of Tic-Tac-Toe, dubbed Bertie the Brain, to show the marvels of electronic computing.
Kates built the game to showcase his additron tube, a miniature version of the vacuum tube, though the transistor overtook it in computer development shortly thereafter.
